19 models built · 17 served
Mistral AI is a French lab founded in 2023, shipping both open-weight and commercial models across the Mistral Large, Mistral Small, and Ministral families. Through OpenKey, 19 Mistral models are available, ranging from the 3B-parameter Ministral 3 3B up to Mistral Medium 3.5. The lineup covers general text and vision models plus specialists: Codestral and Devstral for code, Voxtral for audio-to-text, and Saba for lighter-weight tasks. Pricing spans from $0.02 per 1M input tokens (Mistral Nemo) up to $2.00 per 1M input tokens (Mistral Large, Mixtral 8x22B). None of Mistral's models on OpenKey are free — this is a commercial lineup with tiers for budget, mid-range, and flagship use.
Lineup
For general-purpose work, Mistral Medium 3.5 ($1.50/$7.50 per 1M in/out) is the current flagship, with a 262,144-token context window and text+image+file input. If you're budget-constrained, Mistral Small 4 ($0.15/$0.60) or Mistral Small 3.2 24B ($0.075/$0.20) cover most everyday text and vision tasks at a fraction of the cost. For code, use Devstral 2 ($0.40/$2.00) or Codestral 2508 ($0.30/$0.90). For the cheapest option in the whole lineup, Mistral Nemo runs $0.02/$0.03 per 1M tokens — legacy pricing, but still live. Ministral 3B/8B/14B models ($0.10-$0.20) suit lightweight, latency-sensitive jobs.
